Title: Magnetic storage device with a tracking control system
Inventor: HOENIG ECKHARDT DR
IPC: G11B5/596
Filed: 1988-07-26
Abstract: The magnetic storage device includes a magnetisable storage disc, a read/write magnetic head, which is arranged on a flying element, and a tracking control system. This system has a servo head which is rigidly connected to the magnetic head and can be kept on at least one control track by means of downstream electronics. The storage device is to be designed in such a way that continuous control of its magnetic head can be ensured. For this purpose, it is provided according to the invention that, running along the data tracks (4c), there are separately written into the storage disc (2) control tracks (9, 10), which in each case contain two parallel half-tracks (9a, 9b; 10a, 10b) which have antiparallel directions of magnetisation (13a, 13b), and that the flying element is provided on its rear flat side with the servo head (20), which contains a magneto-resistive sensor (26) which is magnetically coupled to two magnet legs (22, 23), which are assigned to at least one control track (9, 10). <IMAGE>
Patent DE-3833618-A1 (DE)
Title: Digital information transmission system
Inventor: TAMM HENDRYK
IPC: H04L25/49
Filed: 1988-10-03
Abstract: Digital information transmission systems are known in which a main signal to be transmitted is coded with the CMI code and in which an additional signal is transmitted by code rule violations of the main signal. In practice, a synchronicity between main signal and additional signal is in most cases not ensured due to signal jitter. The present digital information transmission system is also suitable for signals with jitter in that further code rule violations are inserted at regular intervals, a particular time interval between code rule violations due to the additional signal and the code rule violations inserted at regular intervals being predeterminable.

Title: Method and appliance for vertical vapour deposition growth
Inventor: OHTO TAKASHI
IPC: H01L21/22
Filed: 1988-11-05
Abstract: An appliance for vertical vapour deposition growth is used in such a way to produce a carrier substrate of a dielectric insulating substrate, that there is applied, to a surface of a semiconductor substrate which is covered with an insulating layer, a thick polycrystalline growth layer by means of a vapour deposition growth method. The appliance is characterised in that a carbon-based material, on whose surface an SiC layer is present, forms a susceptor which is arranged horizontally in a reaction furnace and carries the semiconductor substance. The ratio of the thickness of the SiC layer on an upper side of the susceptor to the thickness of the SiC layer on the underside of the susceptor is from 1:1.1 to 1:1.5.

Patent DE-3839712-A1 (DE)
Title: Cargo ship, in particular a container ship
Inventor: THIELE WOLFGANG DIPL ING
IPC: B63B25/00
Filed: 1988-11-24
Abstract: In the ships referred to here, the requirement is to transport containers (32, 33) of different size in a secured manner in cellular frames. However, it has been found that, in the case of the known cellular frames firmly installed on board, only one load consisting of a certain number of containers (32, 33) of a certain size can be accommodated, but in practice this load will scarcely be available for any particular trip. Therefore the existing stowage space in ships with fixed stowage frames can scarcely be utilised in practice. In addition, it has proven to be problematic to open cellular spaces (37, 38) of different size in the hold (31) without any difficulties for loading and unloading using conventional, movable hatch covers (44). To solve the abovementioned problems, the invention provides a hatch-cover arrangement which has a (larger) rolling cover (46) of conventional type of construction and a (longer) lifting cover (47) which can be shortened by a hinged section (50) for clearing sufficiently large sectional areas of the hold opening (39). Furthermore, cellular spaces of different size of the cellular frame can be formed by cell walls (68) movable in the hold (31) or on the hatch covers (44). The invention is especially suitable for all-container ships (30). <IMAGE>

Title: Reproduction circuit for a SECAM colour television signal
Inventor: KLUTH HANS-JUERGEN DIPL ING
IPC: H04N9/64
Filed: 1989-03-02
Abstract: To reduce the visibility of the colour subcarrier in the picture, a notch filter for the colour subcarrier is located in the path of the luminance signal, as is well-known. This also suppresses useful frequencies of the luminance signal and reduces the sharpness of the picture. The invention is intended to suppress the colour subcarrier optimally but to affect the picture sharpness as little as possible. The filter (7) has an electronically shiftable locking point (8) which is adjusted to the respective instantaneous frequency of the colour subcarrier (F) by the colour difference signals. Especially for a colour television receiver or a video recorder. <IMAGE>

Title: Assembly on heating boiler for redn. of atmospheric effluent - contained inside the exhaust chimney, which introduces fluids to treat ascending gases
Inventor: PARIL HUGO
IPC: F23J15/04
Filed: 1990-03-20
Abstract: When gas or oil is burned in a domestic boiler, this results in the emission of pollutants such as nitrous oxides, carbon monoxide and soot particles. The novelty is that the chimney is fitted with an inner tube made of stainless  steel or glass which has a gas-tight seal with the combustion gas outlet pipe. A spray inlet is fitted to the chimney to facilitate introduction of fluid which treats ascending combustion gases. Fig.1 shows a suitable installation in which the spray jet (11) introduces effluent treatment fluid into the gas outlet inner pipe (4) via an orifice (12) through the chimney wall to generate a spray curtain (16) above the spray inlet. Fluid (7) is introduced by pump (9) where it captures a  substantial portion of the pollutants to condense and fall to the base of the chimney for collection and reuse. USE/ADVANTAGE - This arrangement facilitates the  installation and operation of low cost combustion gas washing to  existing small scale heating plant such as are often found in elderly dwellings, to reduce atmospheric effluent.
